2. Where data comes from? What is it about? Volcanic and Solar Forcing of the Tropical Pacific over the Past 40 years ftp://ftp.ncdc.noaa.gov/pub/data/paleo/climate_forcing/mann 2005/mann2005.txt 1. Tropical Solar Radiative Forcing -Tropical Solar Radiative Forcing, W/m2 in 40 years 1959-1999 2. Tropical Volcanic Radiative Forcing – Tropical Volcanic Radiative Forcing, W/m2 in 40 years 1959-1999

3. What data does this method? The response of El Ni to natural radiative forcing changes over the past 40year is investigated based on numerical experiments employing the Zebiak-Cane model of the tropical Pacific coupled ocean-atmosphere system. Previously published empirical results demonstrating a statistically significant tendency toward El Ni conditions in response to past volcanic radiative forcing are reproduced in the model experiments. A combination of responses to past changes in volcanic and solar radiative forcing closely reproduces changes in the mean state and interannual variability in El Ni in past centuries recorded from fossil corals. The dynamics of El Ni thus appear to have played an important role in the response of the global climate to past changes in radiative forcing. ftp://ftp.ncdc.noaa.gov/pub/data/paleo/climate_forcing/mann2005/mann2005.txt

4. What is the relationship between the data and climate? Volcanic Aerosols Volcanic eruptions can inject large amounts of aerosols into the atmosphere, increasing the earth's albedo (reflectivity) and cooling the climate. http://www.ncdc.noaa.gov/paleo/forcing.html

5. Provide at least one diagram/image of "data" gathered your way which shows how to interpret this kind of data. Data set was from the 1000years ago, however, I cut the data from 1959-1999 to make it simpler and those data became recent data (40years)

9. What data are you collecting? What does the data tell you? What does the data have to do with climate? I collected data of Volcanic and Solar Forcing of the Tropical Pacific over the Past 40 years, and this data tell me that volcanic and solar forces are opposite since solar data contains positive results and volcanic contains negative results. The dynamics of data thus appear to have played an important role in the response of the global climate to past changes in radiativeforcing. There for the climate of recent years had been various with cold and warm weather. Like global warming, THIS made climate change dynamically!
